> Also, fingerprinting isn't always "bad" -- any business who takes credit cards online, wants to try to exclude people who will commit fraud (because they might have done it before.) Preventing fingerprinting, means you prevent certain anti-fraud, which means that you see higher prices and more friction doing commerce online, which also affects your experience. The connection is just much less direct.

By the same argument you could say it should be fine for a physical store to refuse service to anyone who they get a bad feeling about or don't want to serve. But if you permit that then you're immediately opening the door to racism etc., which we consider socially unacceptable. It should be the same for websites too - I bet all these browser fingerprinting techniques just happen to mean better service for people who can afford the latest iphone.
